The Silicon Designs Model 1522 is a surface mount MEMS accelerometer designed for industrial applications requiring enhanced temperature performance. It operates within a temperature range of -55¬8C to +125¬8C and features low noise levels of 7 ¬µg/,àöHz. The device is available in various full-scale acceleration ranges from ¬±2 g to ¬±400 g, making it suitable for a wide array of applications. The accelerometer provides a ¬±4V differential analog output and operates on a +5 VDC power supply with a typical current draw of 5 mA. It is nitrogen damped and hermetically sealed, ensuring reliability in harsh environments. Each unit is individually tested and calibrated in a climate chamber, which guarantees accuracy even under significant temperature fluctuations. The Model 1522 also includes an internal temperature sensor and is RoHS compliant, with serialized units for traceability. Engineers seeking a reliable accelerometer for zero to medium frequency applications, particularly in environments with large temperature variations, may find the Model 1522 to be a suitable choice.
The Model 1522 is an industrial-grade surface mount MEMS DC accelerometer with enhanced temperature performance and a low-cost design. Like the SDI Model 1521, it is designed for use between -55°C and +125°C, however, the Model 1522 has only half the bias and scale-factor temperature coefficients of the Model 1521. Each nitrogen-damped, hermetically sealed Model 1522 accelerometer undergoes individual temperature testing, programming, calibration, and verification within a climate chamber environment to ensure its improved performance in more temperature-intensiv
